In another bout of boredom and partly because I was researching for my fic. I came across a topic on the AS Vivid forums. The topic itself caught my attention because some people claimed it to be a plot hole for the sake of "reincarnation romance."
The topic was "If Vivio is the clone of the Saint Kaiser, why aren't people worshiping the ground she walks on or at least going to see her?"
To me, the question should be "Why is there a church for Olivie in the first place?" We are never given the reason why people revered Olivie, other than the fact that she was the one who ended the centuries-long Belkan wars. If the flashbacks in the current chapters are of any indication, we'll probably get to know how exactly did she accomplish this feat.
People seem to assume that Mid-Childians worship Olivie like she was some kind of deity, but I think their admiration for Olivie stems closer to hero worship than that of a goddess. Granted, Olivie was revered as the strongest combat mage, but she's still human. Hegemon Klaus was another absurdly strong mage who took the title of "strongest mage" once Olivie was gone, and his name is famed in legends as "having the strength of a thousand men," yet we do not have the "Church of Ingvalt." Vivio's school is named "Saint Hilde," yet we have no idea who this person is. Hell, we don't even know why Olivie was given the title of "Sank Kaiser." (did I get that right?) Again, the only thing we know Olivie did was end the Unification Wars, how she ended it is another thing altogether. We are never told if Olivie preached the ideas of peace, fed the people by magically multiplying food, raised the dead, and more importantly, rose from the dead: things that Jesus did. Would Jesus be more popular if he fought the Romans? Probably, but people worship him because he did seemingly impossible things and preached ideas that were highly influential to society.
I think people do not swam and worship the ground Vivio walks on because even if they knew she was Olivie's clone, the best reaction they could probably have is, "Really? Wow!" She'll probably be treated like a celebrity or something similar, but people would still think of her as a human. Mid-childians would react more to the fact that there are people who clone human beings, which is illegal.
Another thing is in Mid-Childa's current age, people do not necessary need the influence of somebody like Olivie to help them live their lives. The fact that the Saint Church itself is experiencing low membership is also something, as Chantez' goal in entering the DSAA tournament is to inspire young children to join the Saint Church because there are kind people there that could help them find their purpose in life. Neither Vivio nor Olivie were responsible for Chantez' joining of the Saint Church; it was Schach. To her, Vivio is simply a special and kind kid, but a kid nonetheless.
To conclude, I think Mid-Chidlians simply view Olivie as a Hero, kind of like Joan of Arc, hence why people aren't flocking in droves to see Vivio.
